Once again I'm unhappy with the service received from the Heidelberg (Gauteng) branch. The technician (Willie) came to install my outside beam, move one of my passives and move my door magnet on the 18/01/2021. He left the door magnet on the floor and my dog got hold of it and chew it up. He installed it just like that and left it open. He told me that he'll come and replace, till now he never came. I've made the manager (Rosemary) aware of it last week and she told me to call him. Please tell me who's responsibility is it to call the technician, because when I call him he doesn't answer his phone and when I've send him a message he doesn't border to respond. I want my door magnet replaced the way he found it. Secondly, ever since he came to replace all these things, my alarm goes off unnecessary at night and most of the nights I have to sleep with it being not activated. I've send her an email regarding that last week and she told me to call Willie, who doesn't answer my calls.What's the use of having an alarm if you can't make use of it. I would've like to cancel my alarm with Fidelity ADT, but because the patrol is so good, that's the ONLY thing keeping me with you. Thirdly, for the years we've been with you, I've asked numerous times, if my alarm goes off, the first contact person should be me Lauren and not my husband, but they've NEVER made the necessary changes. May I please ask for that to be rectified?
